Abstract

<PICT:1057847/C1/1> Sheets of glass heated to deformation temperature are supported by directing gas under pressure against the under-surface from a number of outlets and exhausting the gas from other outlets adjacent some only of the emitting outlets. The emitting outlets are in the form of small chambers 87 arranged in groups separated by passages 89 leading to an exhaust channel. The gas may serve also as a heat-transfer medium for heating or cooling the glass, as during bending over a curved bed and tempering by quenching or rapid cooling.
